L.A. hotel workers could get $15.37 an hour - the highest minimum wage in the U.S.

Hotel worker Sandra Diaz says a $15.37 minimum wage would make a real difference for her family.

Barack Obama wants $10.10. Seattle got $15.

Now, Los Angeles hotel workers might be outdoing them all with the country's highest minimum wage: $15.37 an hour, thanks to a new city ordinance that is expected to pass by Labor Day.

It would be a boon for Sandra Diaz, and 10,000 workers like her, who keep the hotel industry running in L.A. by cleaning rooms, doing laundry, and working the kitchens.

Fresh off a decision by Seattle's city council last month to raise its hourly minimum wage to $15, L.A. lawmakers say the city's booming tourism should translate to higher wages for hotel workers.

It adds up to busy workdays for Diaz. The 30-year-old mother spends most mornings clearing tables and taking hundreds of dirty plates to the dishwasher at a restaurant in Starwood's(HOT) Westin Hotel near the Los Angeles airport. She's been doing it for 11 years, after finding a job soon after arriving in the U.S. from Mexico.

Diaz's hourly wage is currently $12.16, a full 25% more than the current $9 minimum wage in California.
